Appearance and anatomy

Upside-down catfish are small, reaching a maximum of 9.6 centimetres (4 in). Upside-down catfish are adapted to spending most of their time upside-down. This is reflected in the fish's pigmentation—their bellies are darker than their backs, a form of countershading. Exotic Tropical Fishes, , Herbert R., Axelrod, T.F.H. Publications, 1996,

Ecology

These fish are mostly nocturnal, and feed on insects, crustaceans, and plant matter. These fish lay eggs. The young fish do not swim upside-down until they are about two months old. Aquarium Owner's Guide, , Gina, Sanford, DK Publishing, ,

In the aquarium

The upside-down catfish is well suited to aquariums because of its small size (typically 9 or 10 cm or less) and peaceful demeanor. It fares best in schools of up to half a dozen.
